Sleeping for less than 7 hours regularly up your risk of heart diseases: Study

In a new study published in the Journal of Experimental Physiology, the researchers revealed that chronic short sleep is associated with increased risk of clogged arteries, heart disease, and thus increased morbidity and mortality.

Researchers claim to have figured out why lack of sleep increases susceptibility to heart diseases.According to the study published in the Journal of Experimental Physiology, chronic short sleep is associated with increased risk of clogged arteries, heart disease, and thus increased morbidity and mortality.

Doctors have also identified the patients who might need to change their habits before they develop the disease. In adults who regularly slept fewer than 7 hours per night, the levels of certain microRNAs (molecules that influence whether or not a gene is expressed) were lower.

These molecules play a key role in regulating vascular health and thus their levels are now recognised to be sensitive and specific biomarkers of cardiovascular health, inflammation and disease. In other words, a lowered level of these molecules is associated with heart disease, so they could be used as a biomarker to determine who is more susceptible to disease.
